454//
455// x-axis: Offset (Parameter 0 of the polynomial)
456// y-axis: Slope (Parameter 1 of the polynomial)
457//
458// The offset is a measure of how well-known the supposed additional contributions
459// to the value "reduced sigma" are. Because a photo-multiplier is a linear instrument,
460// the excess fluctuations are linear w.r.t. the signal amplitude and can be expressed by
461// the proportionality constant F (the "F-Factor").
462// Adding noise from outside (e.g. night sky background) modifies the recorded noise, but
463// not the mean extracted signal, due to the AC-coupling. Thus, noise contributions from outside
464// (e.g. calculating the pedestal RMS)have to be subtracted from the recorded signal fluctuations
465// in order to retrieve the linearity relation:
466//
467// sigma(signal)^2 / mean(signal)^2 = sigma^2 / <Q>^2 = F^2 / <n_phe> (1)
468//
469// Any systematic offset in the sigma(signal) will produce an offset in the "Razmik plot"),
470// characterized by the Offset of the polynomial fit. Thus, in an ideal case, all pixels have their
471// "offset" centered very closely around zero.
472//
473// The "slope" is the proportionality constant F^2, multiplied with the conversion factor
474// phe's to mean signal (because the "Razmik plot" plots the left side of eq. (1) w.r.t.
475// 1/<Q> instead of 1/<n_phe>. However, the mean number of photo-electrons <n_phe> can be
476// expressed by <Q> with the relation:
477//
478// <n_phe> = c_phe * <Q> (2)
479//
480// Thus:
481//
482// 1/<n_phe> = 1/c_phe * 1/<Q> (3)
483//
484// and:
485//
486// Slope = F^2 / c_phe
487//
488// In the ideal case of having equal photo-multipliers and a perfectly flat-fielded camera,
489// the "slope" -values should thus all be closely centered around F^2/c_phe.
